I have to say that I like the streaming style interface. The only drawback that jumps out at me is that every time I look at it, it _feels_ like I would be able to do something like:
svg_plot my_plot("./image.svg");
my_plot << image_size(500, 200) << x_scale(-7, 9) << draw_axis(); for (double i = 1.0; i < 10; i += 1.0) { my_plot << i; } my_plot << write();
Or can I??
Currently, no. However, I don't see why I couldn't add that before my midterm release in July :)
Feedback / use cases welcome ;).
In my situation the data that I might want to visualize isn't directly usable (well, meaningful) without interpolation between the data points. With the combination of the extractor suggested by Matias and support for SVG's Bézier curves then I could output a plot that is more representative of the actual data. I'd also like to second Paul Bristow's suggestion for auto scaling, if I already knew what was in the container then why would I need to "visualize it" :-}
I haven't gotten a chance to look at the Bézier curves yet that SVG supports. The look is definitely something that I'd want to allow people to have ( sin(x) would look pretty hideous without a large number of points). And Paul and Matias' suggestions are part of my vision for how this project will end up, so don't worry about that :)
